偷蛋龙科（Oviraptoridae）又名窃蛋龙科，是群类似鸟类的手盗龙类恐龙，具有类似鹦鹉的喙状嘴，嘴部没有牙齿，某些物种具有纤细的头冠。偷蛋龙科的化石主要被发现于蒙古与中国的戈壁沙漠，但是单足龙亚科、更原始的小猎龙可能属于偷蛋龙科，牠们多生存于北美洲。偷蛋龙科的体型小，经测量后，大部分个体的身长介于1到2公尺；某些可能属于偷蛋龙科的化石，体型更为大型。偷蛋龙科首次出现于晚白垩纪的森诺曼阶，约8400万年前，这是最可靠的数据；而可能是偷蛋龙科的小猎龙被发现于早白垩纪的阿普第阶。偷蛋龙科在马斯垂克阶末期灭绝。

Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs. Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests. They were generally small, measuring between one and two metres long in most cases, though some possible oviraptorids were gigantic. Oviraptorids are currently known only from the Late Cretaceous of Asia, with the most well-known species and complete specimens found only in the Gobi Desert of Mongolia and northwestern China.
